Abstract

Background: Cannabis exposures reported to the California Poison Control System increased following the initiation of recreational cannabis sales on 1 January 2018 (i.e., "commercialization"). We evaluated whether local cannabis control policies adopted by 2021 were associated with shifts in harmful cannabis exposures.

Methods: Using cannabis control policies collected for all 539 California cities and counties in 2020-2021, we applied a differences-in-differences design with negative binomial regression to test the association of policies with harmful cannabis exposures reported to California Poison Control System (2011-2020), before and after commercialization. We considered three policy categories: bans on storefront recreational retail cannabis businesses, overall restrictiveness, and specific recommended provisions (restricting product types or potency, packaging and labeling restrictions, and server training requirements).

Results: Localities that ultimately banned storefront recreational retail cannabis businesses had fewer harmful cannabis exposures for children aged <13 years (rate ratio = 0.82; 95% confidence interval = 0.65, 1.02), but not for people aged >13 years (rate ratio = 0.97; 95% confidence interval = 0.85, 1.11). Of 167 localities ultimately permitting recreational cannabis sales, overall restrictiveness was not associated with harmful cannabis exposures among children aged <13 years, but for people aged >13 years, a 1-standard deviation increase in ultimate restrictiveness was associated with fewer harmful cannabis exposures (rate ratio = 0.93; 95% confidence interval = 0.86, 1.01). For recommended provisions, estimates were generally too imprecise to detect associations with harmful cannabis exposures.

Conclusion: Bans on storefront retail and other restrictive approaches to regulating recreational cannabis may be associated with fewer harmful cannabis exposures for some age groups following statewide commercialization.

地方大麻管制政策与向加州毒物控制系统报告的有害大麻暴露的关联。
背景:2018 年 1 月 1 日开始娱乐性大麻销售(即 "商业化")后,向加州毒物控制系统报告的大麻暴露有所增加。我们评估了 2021 年采取的地方大麻管制政策是否与有害大麻暴露的变化有关:利用 2020-2021 年收集的加利福尼亚州所有 539 个市县的大麻管制政策,我们采用负二项回归的差分设计来检验商业化前后政策与向加利福尼亚州毒物控制系统报告的有害大麻暴露(2011-2020 年)之间的关联。我们考虑了三个政策类别:禁止店面娱乐零售大麻业务、整体限制性和具体建议条款(限制产品类型或效力、包装和标签限制以及服务器培训要求):最终禁止店面休闲零售大麻业务的地方,13 岁儿童接触大麻的有害程度较低(比率 = 0.97;95% 置信区间 = 0.85,1.11)。在最终允许娱乐性大麻销售的 167 个地方中,总体限制性与 13 岁儿童接触有害大麻的情况无关,最终限制性每增加 1 个标准差,接触有害大麻的情况就会减少(比率 = 0.93;95% 置信区间 = 0.86,1.01)。对于建议的规定,估计值通常过于不精确,无法检测出与有害大麻暴露之间的关联:结论:禁止店面零售和采用其他限制性方法监管娱乐性大麻可能与全州范围商业化后某些年龄组的有害大麻暴露减少有关。
